To make the Philadelphia Streets Department's 8th Annual Philly Spring Cleanup successful, we needed to get the word out and invite everyone to pitch in. We leveraged paid and organic social media to connect with Philadelphia residents, invited them to submit ideas to help clean up the City, and encouraged them to volunteer to help keep their own neighborhoods clean and beautiful. We asked... and the City's residents answered. More than 1,700 social posts from residents, CDCs, and civic and community groups helped us spread the word beyond the potential 900,000 users reached during that time. Thanks to regular tweeting and sharing across platforms, these individuals, community groups, and partner organizations helped connect with more than 1.1 million users to get involved.

But that's not all. These combined efforts led more than 14,000 volunteers to donate 72,300 service hours in official Philly Spring Cleanup projects in 723 sites citywide – making the 8th Annual Philly Spring Cleanup the largest in history! In that one-day cleanup on April 11, 2015, volunteers cleaned up more than 400 tons of trash and more than 50 tons of recyclable materials in their neighborhoods.
